LINER, FOR PNEUMATIC TIRES.

Application filed December 14, 1914.

To will 'whom 'it may conf/ern.'

lic it known that l, Fiunss lil. NEAL, a citizen oi' the United States, residing at Anderson, in the county of Madison and State ot Indiana, have invented certain new and useful improvements in Liners for Pneumatic Tires; and do declare 'the following to be a full, clear-and exact description of the invention, such, as will enable others skilled inthe part to which it appertains to m'ake and use the saine.

My invention relates broadly to improvements in pneumatic tires and more ijiarticularly to means for preventing puncturing thereof.

The inain object of the invention is to provide an extremely simple liner which may be applied between the outer casing and inner tube of practically any pneumatic tire, and to so construct this liner as to prevent puncturing of the tube. ln carrying out this object, a central retaining ring is provided, and inner and outer series of curved plates are hingedly connected at their inner ends to said ring, said plates extending laterally in opposite directions from the ring and beingso curved as to conform to the transverse curvature oir the tire.

A. further object of the invention, ther fore becomes to so construct these plates, as to 'form the inner'and outer plates which project to each side of the ring, oi' single and individual sheets of metal so bent as to form knuckles which pass around said ring and unite the inner and outer plates.

lVith the above and minor objects in view, the invention resides in certain novel features oi' construction and combination. herein described and claimed and shown in the drawings wherein Figure l is a side elevation, partly in section. showing` the application ci a. portion of the liner to a portion of a tire; Fig'. 2 is a vertical transverse section as s'een on the line 2 2 of Fig. l; Fig. 3 is a plan view of a portion of the liner with its coveringv re- Inovcd; Fig. l is a perspective of a portion of the liner in the condition seen in Fig. 3 and showing' a number of the plates separated one from the other; li ."3 is a detailsection as seen on the line 5-5 of 3; and Fig. ti is a plan view ot' one of the blanks from which the protecting plates are formed.

ln these drawings, 'forming a part ci this application, a tire casing C and an inner Specification of Letters Patent.

i knuckles S, are foi-ined.-

tube T are shown, both of these members being of connnon construction, interposed between the casing' and tube, is my improved liner 1 which is constructed as hereinafter described.

rThe liner l comprises an attaching ring 2 which extends circumferentially around the tire between the tube and casing, an inner series of curved plates 3 which project latorally in one direction'frorn the ringl 2, a second inner series of curved plates 4 which project laterally from said ring in the opposite direct-ion, an outer series of curved lates which overlie the plates 3, and a second cuter series of curved plates which overlie the inner platos 4. is seen more particularly in Fig. 5, the centers of the plates 5 and 6 overliethe spaces between the adjacent edges of the inner plates 3 and 4 or, in other Words, the outer plates break joints with the inner plates.

As roost clearly seen' in Fig. 4, the inner ends of the plates 3 and 5 are connected by knuckles 7 which embrace and are spaced upon 'the ring 2, while the plates 4 and 6 are connected at their inner edges by inten'ral knuckles 8 which likewiseeinbrace the ring and which are interposed between the knuckles 7, By such construction, a. device is provided which will be practically puncture-proof. and which possesses no spaces through whichy objects might be projected to puncture the tube T.

The structure just described is preferably equipped with a split canvas tube 9 which is cemented or otherwise secured to its inner side, and with a canvas covering l0 which is secured in any suitable manner to its outer side, said covering, l0, having its edges secured at 11 to the tube 9, while the latter practically encircles the tube T to protect its sides as well as its tread portion.

In order to more clearly illustrate the manner in which the inner plates 3, the outer plates 5 contacting therewith, and the knuckles 7. uniting the two are formed, Fig. 6 is provided, which figure shows a blank of metal from which these plates and knuckles. as well as the plates 4- and 6 and the The two plates are then bent one 'toward the other around the ring' 2, to form knuckles and to constitute the inner and outer protecting plates above described.

From the foregoing description, taken in connection with the accompanying drawings,

it will he seen that very simple strncture has beeny provided for carrying out the objects, o1 vthe invention, yet that the eeiencyandfdurability of the liner is not irn- I claimt' A tire shield comprising a single ring and paired loy-A sulziasimplicity.

y two annular series of umts disposed one series 0n each s'de ofvsaid ring, each unit comprising inner and outer rectangular plates of substantially equal area', one half .ofthe width of the inner plate beingv overlapped by one half of the Width of the outer l plate, and a knuckle uniting and formed integrally with the inner ends of the overlapped halves of the plates, the knuckles,

In testimony whereof I have hereunto set my hand in presence of two subscribing Wit- FINESS E. NEAL.k
